A photograph contains only about 42 bytes of information, argues Toby Ord

The origin of this thread: Toby Ord argues in 'Curating the World' that a photograph contains very little information — about 42 bytes — and that understanding why changes how we see photography. summerstay1 replies that you can view it via the compressed text prompt needed to reproduce a photo: a few hundred bytes, a few paragraphs, assuming the model knows the subjects. The thread explores photo information content, model memory, and whether prompts define artistic contribution.
